Abstract
A spring (9) is installed on a button (10), a hard magnetic block (8) and input contacts (7) and (11) are arranged on the lower portion of the button, a soft magnetic block (3) corresponding to the hard magnetic block, lower contacts (2) and (5) corresponding to the contacts (7) and (11) are arranged on a base below the button, a PTC heating body (4) is arranged below the soft magnetic block (3), and the heating body (4) is connected with the lower contacts (2) and (5). The lamp has the advantages of simple structure, reliable work, convenient use and avoiding energy waste of the 'incandescent lamp'.
Description
The utility model relates to a kind of control switch of illuminating lamp, particularly a kind of illumination time-delay with the automatic controlled function of time-delay.
At present, illuminating lamp adopts manual two-position switch control usually, at the special requirement of public place and some occasion, people have designed polytype delay switch, and the mode of automatic control time-delay is had nothing in common with each other, avoided " altar lamp " waste electric power, play great role, and easy to use, but its complex circuit, cost is higher, is difficult to large-scale popularization and uses.
The purpose of this utility model provides a kind of new illumination time-delay, and it is simple in structure, and control is sensitive reliable, easy to use.
The purpose of this utility model can realize by following measure: on this switch knob back-moving spring is housed, the bottom of knob is provided with Hard Magnetic piece and power supply input contact, be provided with the soft magnetism piece at base and the corresponding position of knob Hard Magnetic piece, be provided with lower contact with power supply input corresponding position, contact, under the soft magnetism piece heater is housed, heater is connected with lower contact.Power supply connects the input contact of knob, the output lower contact connects electric light, when pressing knob, and Hard Magnetic piece and the adhesive of soft magnetism piece, input contacting lower contact, the electric light electrified light emitting, the heater conducting heating under the soft magnetism simultaneously is when its temperature reaches the Curie temperature of soft magnetism, soft magnetism piece loss of excitation, the Hard Magnetic piece breaks away from, and knob resets, and cuts off lamp and heating unit power.
Concrete structure of the present utility model and embodiment are provided by the following drawings:
Fig. 1 is the structure chart of illumination time-delay;
The control circuit figure of illumination time-delay on Fig. 2.
The utility model is described in further detail below with reference to accompanying drawing: with reference to Fig. 1, spring ［ 9 ］ is housed on the knob of switch ［ 10 ］, the effect of spring ［ 9 ］ is to go up to push to turn round to reset, be provided with Hard Magnetic piece ［ 8 ］ and power supply input contact ［ 7 ］ in the bottom of knob, ［ 11 ］, knob can move up and down, base below knob ［ 1 ］, it is corresponding with Hard Magnetic piece ［ 8 ］ to be provided with soft magnetism piece ［ 3 ］, be provided with lower contact ［ 2 ］, ［ 5 ］ respectively with the input contact ［ 7 ］, ［ 11 ］ corresponding, be provided with heater ［ 4 ］ below the soft magnetism piece ［ 3 ］, heater ［ 4 ］ can adopt the PTC thermistor, this switch can be joined two-position switch and be used, and can lead directly to the conducting of also can delaying time, and the control circuit figure of its connection sees Fig. 2, input contact ［ 7 ］ connects K
1The A point, K
1B point connecting terminal ［ 2 ］, K
1When connecting the B point, directly turn-on lamp is luminous, K
1When connecting the A point, lamp is controlled by delay switch, when pressing knob ［ 10 ］, Hard Magnetic piece ［ 8 ］ and soft magnetism piece ［ 3 ］ adhesive, contact ［ 7 ］, ［ 11 ］ make contact ［ 2 ］, ［ 5 ］, the lamp conducting is luminous, heater ［ 4 ］ conducting heating simultaneously, when its temperature reaches the Curie temperature of soft magnetism piece, soft magnetism piece loss of excitation, the Hard Magnetic piece breaks away from, and knob resets.
Of the present utility model simple in structure, utilize the effect of magnetic to realize control automatically, reliable operation, control is sensitive, and the various applications that suitable time-delay is turned off the light not only make things convenient for use but also can avoid " altar lamp " energy waste.
